Very nice, thanks. So Greenland's area is about 2 million km^2 and the area of all oceans is about 360 million km^2, so the average thickness of the ice on Greenland is roughly 24 feet * 360/2 = 1.3 kilometers. That's an unimaginably huge amount of ice! Apparently the thickest point is 3 km! https://en.wikipedia.org/wiki/Greenland_ice_sheet
